PMID 29410559WHAT IT FOUND
Adding Flexi-Bar vibration exercises to standard physical therapy reduced pain and disability more than standard therapy alone in patients with chronic low back pain.
Key findings
01The experimental group showed significant reductions in pain and disability scores compared to the control group.
02Both groups received identical standard physical therapy interventions, with the experimental group adding Flexi-Bar exercises.

What it does not show
The study had a small sample size of 30 participants, which limits the generalizability of the findings. The study did not account for differences in patients' physical characteristics and daily habits, which could influence recovery. The intervention was not blinded, and patients knew they were receiving the additional exercise component.
Declared interests
No conflicts of interest or funding sources are declared in the text.
The easy way to misread this
Do not attribute the pain reduction solely to the Flexi-Bar vibration exercises, as both groups received standard physical therapy interventions including thermotherapy, electrotherapy, and ultrasonic therapy.
